Laser spectroscopy - Laser spectroscopy
Spectroscopy using laser light. Spectroscopy is a science that aims to detect various properties of materials by shining electromagnetic waves on them and investigating the interactions between them. The response of materials is mainly observed as spectral lines. Important factors in measurement are how close together the spectral lines can be separated and observed (resolution), how weak the spectral lines can be observed (sensitivity), and how accurately the position and intensity of the spectral lines can be determined (precision). In conventional spectroscopy, these were limited by the performance of the spectrometer.

Japanese:
レーザー光を利用した分光学。分光学とは,電磁波を物質にあててその間の相互作用を調べ,物質のさまざまな性質を検知しようとする学問である。物質の応答は主としてスペクトル線として観測される。この際どれだけ接近したスペクトル線まで分離して観測できるか(分解能),どれだけ弱いスペクトル線まで観測できるか(感度),スペクトル線の位置や強度をどれだけ正確に決められるか(精度)が測定上の重要な要素となる。従来の分光学では分光器の性能がこれらを制約していた。
